The next day, everyone expanded the search area around the missing fishing boat.

Finally, I saw the scattered wreckage of the ship, and several crew members wearing floating rings lying on the wooden board and shouting for help.

Everyone's eyes lit up, and they rushed to rescue them ashore.

They had been floating on the sea for a day and a night, and they were thirsty and hungry, and they were separated from each other.

Gudongdong drank a lot of water before someone answered the question.

On the way back, the fishing boat encountered a dragon sucking water, and the fishing boat was instantly thrown into it by lightning.

They were in Class A at the time, and they were lucky enough to escape being thrown out by the dragon sucking water.

The rest of the people in the cabin seemed to have sunk to the bottom of the sea.

Hearing this, the atmosphere was extremely heavy, and it took a long time for the subordinate to ask Wang Qiong, "General, are you still looking for it?"

Wang Qiong looked at the endless sea, "Look! Keep looking! If they are still alive, but they can't wait for the hope of the next life, how hopeless it would be."

"Yes!"

Another search and rescue ship returned, and the relatives of the crew stood up again and watched excitedly, hoping to see their husband and son on board.

When the search and rescue ship docked, five familiar figures appeared, and everyone was excited, "I found it, I found it!"

I was happy for a moment, and learned that there were only five people who came back. Except for the relatives of the five crew members who still had smiles on their faces, the rest of them all cried out.

Wang Qiong reassured them, "We will definitely not give up the search and rescue, please rest assured."

Even people and boats sank to the bottom of the sea, so how could they survive.

Everyone knew it was impossible, but they still held on to the last glimmer of hope that they would survive.

When Bai Wutong heard that the ship sank, only five people were recovered, and eighteen people were still missing, a story popped up in his mind, Robinson Crusoe.

What if they were involved and ended up on a deserted island.

The exact number of islands around Baye has not yet been fully counted.

Bai Wutong asked Wang Qiong and the others to search the surrounding islands. After searching for about ten days, when the relatives completely lost confidence and the court was preparing for the follow-up pension, Ami took Song Benhua to see the sea of ​​stars, and accidentally found a homemade raft. Three missing crew members trying to row towards the mainland.

Ami and Song Benhua rushed to rescue them on board, and they said: "There are still ten people on the island, waiting for everyone to rescue them."

When they woke up, they were trapped on a small island. The island was so small that there was no fresh water for human survival. They worked together to make a strong raft and rowed to the current island in batches.

This island has water, and the seafood, fruits and vegetation are relatively abundant. They collected some and prepared to go ashore. They found that the wind direction here is opposite to that of the mainland, and the bamboo raft encountered frequent torrents and could not cross it.

For safety, they could only wait patiently and hoped that the court would find them.

Just half a month passed, the court did not come, and finally waited for a chance to pass with the wind.

Therefore, it was decided that the three people with the best water skills would go back to report the news first, and then come to rescue them.

Coincidentally, they met Ami and Song Benhua again.

Song Benhua took out the picture book, marked the location of the island, took the three of them back, and quickly reported to Wang Qiong.

Survivors reappeared, Happy City boiled.

All ten people on the island were taken ashore, and the whereabouts of five crew members are still unknown.

The hopes of their family members were raised, but they failed again. The white-haired woman sat on the ground and cried, "God, can you tell me where my son is!!"

"Give me a letter, let me find my son, can you woo woo woo..."

Everyone can only comfort her, maybe her son will come back one day, just like these people, who was suddenly discovered and returned to her safely.

This incident made Bai Wutong realize that the progress of communication must be accelerated.

When the ship goes out to sea, there is a natural vision. If there is communication equipment, it will notify everyone to return quickly, and perhaps the tragedy of the five families will not be caused.

With convenient communication methods, no matter where you are,

It can connect everyone closely.

The principle of the telephone is that through the conduction of current, the spiral wire will emit noise, and the sound wave of the change of current intensity can be simulated to realize the transmission of language.

After Bai Wutong made up his mind to let everyone use the communication equipment as soon as possible, he designed the hearing aid box when he returned home, mainly composed of a microphone and a receiver.

Although it is very simple, Bai Wutong has been busy in the laboratory of the Empress' Mansion for a long time, even ignoring food.

Chu Tianbao knocked on the door, imitating the heroine in the movie, "Honey, it's time to eat."

Bai Wutong didn't even look back, "I'll be here right away."

Chu Tianbao stood at the door, urging her silently.

Bai Wutong looked back at him helplessly, put down the microphone that was almost finished, "I'm here."

After eating, Bai Wutong plunged into the laboratory again, and Chu Tianbao watched quietly by the side without disturbing.

Until Bai Wutong exclaimed, "It's done!" Without waiting for Chu Tianbao to ask, Bai Wutong put the receiver to Chu Tianbao's ear, picked up the transmitter himself, and softly called out, "Husband~"

Bai Wutong's voice came clearly from the receiver, Chu Tianbao's eyes lit up, and he blurted out, "You developed a telephone?"

Bai Wutong smiled, "Well, this is the most primitive telephone principle. If you improve it, you can use wireless phones, smart phones, investment phones, etc."

Chu Tianbao carefully looked at it curiously, and Bai Wutong explained it in detail, "Take the receiver and try it in the room at the end of the corridor to see if you can hear it."

Chu Tianbao did as he did, covering the receiver with his ears all the way to the room at the end of the corridor.

"Husband, Tianbao, can you hear me?"

Chu Tianbao replied subconsciously, "Yes."

He suddenly discovered that this was just a single receiver, not the mobile phone Bai Wutong gave him, and he could not reply in two directions for the time being.

Chu Tianbao and Bai Wutong poked their heads out at the same time tacitly, and couldn't help smiling.

"Can you hear me?"

"Um."

Bai Wutong took the telephone device to the scientific research laboratory that day, and provided the blueprint of the wireless phone, and asked He Jinchuan to be in charge of the telephone device, which fit the current situation and spread to thousands of households at the fastest speed.

The communication distance of a simple telephone box is only a few tens of meters. If you want to expand the communication range, you have to rely on the construction of signal poles.

He Jinchuan asked people to speed up the production of the phone style requested by Bai Wutong, and then led people to build signal poles in the office area of ​​Xiaoyao City.

Everyone asked him what he was doing out of curiosity. Thinking of life after the popularization of telephones, He Jinchuan couldn't help but proudly said, "The empress has developed a magical way of calling, and the voices of relatives and friends can be heard thousands of miles away."

The scene was quiet for a moment.

Even if Bai Wutong is powerful, it's impossible for him to be this powerful.

Shouldn’t it be God who can do this?
